How to use #b6f978

Derived from its contrast, chroma and lightness — not from taste.

Works well for
  • Text and icons on dark surfaces
  • Primary buttons and calls to action
  • Focus rings, active and selected states
  • Card and section backgrounds
  • Brand accents, badges and data highlights
Use with care
  • Text of any size on white — fails WCAG AA
  • Full-page backgrounds — tiring over long sessions
  • White text placed on it
  • Status meaning — pair it with an icon or label, never colour alone
  • Pairing with a same-lightness hue — edges vibrate
Minimum size as text on white
Not as text
Safe as a fill behind white type
No — use #3D7A05
Safe as a 1px border on white
No — use #55A807

Meaning and mood

What a colour in this family tends to signal, and how this particular chroma and lightness change the reading.

safegrowingnaturalpermissive

Green means go, well, and grown. It carries finance, sustainability and health with almost no explanation needed.

At this chroma the association is amplified — it will dominate anything placed beside it, so give it space and use it sparingly. The lightness keeps it airy and approachable.

Worth knowing

Red/green pairs are the most common colour-blindness failure — never let the two carry meaning alone.

What each alpha value actually composites to. The top row is #b6f978 over white; the bottom row is the same alpha over a checkerboard, so you can see what survives on a photo or a video.

Bottom row of hexes is the flattened result over white — use those when a design tool refuses transparency, or when you need a solid fallback.

#b6f978, answered

What color is #b6f978?

#b6f978 is a light electric green, closest to Green Yellow (ΔE2000 6.6). It sits at 91° on the hue wheel with 92% saturation and 72% lightness, which reads as neutral.

What is the RGB value of #b6f978?

rgb(182, 249, 120) — 182 red, 249 green and 120 blue out of 255, or 71.4% / 97.6% / 47.1% by channel.

What is #b6f978 in HSL and HSV?

hsl(91, 92%, 72%) and hsv(91, 52%, 98%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #b6f978 a light or a dark color?

It is a light color. Relative luminance is 0.7905 and perceived brightness is 86%, so black text on it reaches 16.81:1.

Should I use black or white text on #b6f978?

Black. It scores 16.81:1 against #b6f978, versus 1.25:1 for white — AAA at any size.

Is #b6f978 accessible on a white background?

#b6f978 on white scores 1.25:1, which fails WCAG AA at every size. Darken it to #438606 to reach 4.5:1, or #326404 for 7:1.

What is the complementary color of #b6f978?

#BB78F9 sits directly opposite on the wheel. Softer options are the split-complements #7B78F9 and #F978F6, which give the same contrast with far less vibration.

What colors go well with #b6f978?

For interface work: #F7FAF4 as the surface, #D5EDC0 for borders, #719B4B for secondary text, #9A75FC as an accent and #3D7A05 for hover and pressed states. For a palette, the analogous pair #F6F978 and #78F97B stays calm, while #BB78F9 is the loudest partner.

What is #b6f978 in CMYK for printing?

cmyk(27%, 0%, 52%, 2%). This is a screen-to-ink approximation — a color this saturated sits outside most CMYK gamuts and will print duller than it looks here.

Is #b6f978 warm or cool?

Neutral — it scores 50 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #E5F978; nudged cooler, #86FA77.

Which Tailwind color is closest to #b6f978?

The lime family — its 500 step is #84cc16, ΔE2000 11.8 away. That is a visible difference, so define #b6f978 as a custom token rather than reaching for the built-in.

How do I use #b6f978 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#b6f978] or text-[#b6f978], or register the whole ramp under theme.extend.colors.brand so you get bg-brand-500 and friends. The generated 50–950 scale on this page is ready to paste into your config.

What is #b6f978 with 50% opacity?
